Application led Hatch 12, 1904. Serial. No. 197,846,

To all whom it may concern:

Be it known that I, GEORGE C. Barnum, a citizen of the United States,residing at Oklahoma city, in the county of Oklahoma and Territo ofOklahoma, have invented a new and userfvul Machine or Exposing andDeveloping Photographic Film, of which the iollowing is a full, clear,and exact description, reference being had to the accompanying drawings.

The object of the-'invention is to provide a single machine which willhold a supply of sensitive paper, celluloid, or other suitableihn, whichwill make the exposure to the light necessary to produce the hotographicimage on said iilIn, which will) subject the {ihn after exposure to thenecessary developing, fixing, and washing agents, and which will deliverthe lilm in the form o separate finished photographic prints. Y The newmachine attaches to a camera after the manner of the common plate-holderY larger than the usual plate-holder or even the camera is providedwithA a shelf or support upon which the carnera rests.

ln using the machine a supply of continuous-roll sensitive lilm isplaced within it and by a pair of gripping-rollers i's drawn through anexposing-chamber and fed between-.two endless aprons. These aprons aremounted upon rollers in such manner as to lie in gripand they ass inproper order through the several deve oping, fixing, and washingsolutions, the exposed ilm being carried entirely through said solutionsbetween said aprons. 'l

Other obj ects and advantages of the invention will be set forth in theensuing description. Y A

Referring to the drawings, Figure 1 is an elevation of the machineattached to a camera, parts being cut away toV expose interiorconstruction and the camera in this instance being the style in which 'areilecting-mirror is employed to invert the image. Fig. 2 is an of theportion that is cut away in the right-hand portion of Fig. 1. anelevation of the op and its adjacent parts s own in the left-handportion of Fig. 1. taken on the line A A, Fi 1. Fig. 5 is an elevationofthe right-han end of the structure shown in Fig. 1. Fig. 6 is a detailto be referred to later. .7 is an elevation of the developing-tray andmost of its' attached Fig. 3 is; site end of a roller Fig. 4 is asectional view p parts, taken in the same -direction as Fig. 1, partsbeing out away to expose interior construction. Fig. 8 is a plan View ofthe parts shown in Fig. 7. Fig. 9 is a sectional view taken on the lineB B, Fig. 8; and Fig. 10 is a perspective'view ci the inclosing casingof the machine, Figs. 3 and 6 being on a larger scale and 10 on smallerscale than the other iigures.

Referring to the several figures, in all of which like characters ofreference designate like parts, the main body of the structure consistsof a wooden casing 1, 'into which a drawer portion 2 lits with rabbetedjoints to make it light-proof. The body 1 has a shelf 3, upon which thecamera 4 rests', and is provided with an exposing-chamber 5, similar tothe ordinary plate-holder. 5 has the usual flange or nipple 6 to fltinto the camera, and is provided with the lightexcluding slide 7. Theexposing-chamber 5 has a back wall 8, which acts as a backin for the:film while being exposed, Vand bac of said wall is a film-chamber 9,provided with a door or removable top 10. 'The film-chamber 9 isprovided with a metal bracket 1 1 and an elastic sheet-metal arm 12for-holding a spool 13, u on which a supply of lilm is wound, the racketbeing secured to the side wall of the chamber and the arm to the bottom.The pintles 14 of the spool 13 pass through eyes in the bracket 11' andarm 12,

from which said pintles are removable byA springin said arm outward, andthe elastic force of t e arm 12 presses the spool13 against the bracketand gives said spool a dra ging motion to keep the film 15 taut whileeing exposed or drawn through -the exposingchamber 5.

The main body ofthe structure is provided with a drawer 2 aforesaid, andin said drawer a developing-tra 16 and all parts attached to it aremounte the legs 17 of the tray resting upon the drawer-bottom. Thev tray16- -and all parts attached to it are removable from the casin 1 withthe drawer 2 without the necessity o? disconnecting any part of themachine whatever, and said tray is divided into as many compartments asthere are developing solutions used, of which in the present mstancethere are three, and each compartment has a illing-unnel 18 andemptying-cock 19. The tunnels 18 and cocks 19 are mounted upon theoutside face of the drawer-front 2, and their tubular stems extendthrough said front and are screw-thread- The chamber IOC IIO

ed into protuberated openings 20 and 21, re'

spectively, in the top and bottom of the cornpartments, thereby securingsaid tray to the drawer-front. Mounted within the tray 16 is asheet-metal framework 22, composed of the side portions 22", thecross-bars 22", and the sheet-metal diaphragm 22d. The side ortions 22bare each provided with openottomed slots 22e and 22f, which form theportions between them into downwardly-extending fingers reaching welltoward the bottom of the tray 16, the slots 22"I straddling thepartitions 16b and 16c between the tray-compartments. the side pieces22b are provided with arms 22h, extending upward and outward over theend 16d of the tray and revolribly supporting.

the vend pintles 26b of a main a ron-driving roller 26, Said framework22 a so carries a small roller 23 at its o posite end, whose pintles arej ournaled in t e sides 22h, a series of rollers 24, whose pintles arejournaled in the lower ends of the finger portions 22g to lie close tothe bottom of the tray, and the small roller 25, mounted across theupper edge of the diaphragm 22d, with its end pintles journaled in thelugs 22. The tray 16 in turn supports a main apron-driving roller 36,whose end pintles are journaled in the lugs 16e, integral with andprojecting from the end wall 16d, the small rollers 27 and 28, mounteddirectly over its end walls 16l and 16I and journaled in the lugs 16eand 16g, the like rollers 29 and 30, j ournaled directly over thecompartment-partitions 16b and 16c in the lugs 16h, a series of likerollers 31 mounted in each compartment, with their pintles resting uponcleats 32, riveted to the tray,-l walls, and the roller 33, journaleddirectly under the end wall 16f in the legs 17. The slots 22e of theside pieces 22b straddle the pintles of the rollers 31, which rest uponthe cleats 32 and retain said pintles in proper position.

Two quincuncially perforated endless aprons 34 and 35, of suitablematerial, preferably thin celluloid, travel upon the several rollersasfollows: Starting between the two rollers 23 and 28, which grip theaprons together in obedience to means hereinafter described, said apronstravel'in contact with each other downward and under one of the rollers24, upward and over one of the rollers 31, downward and under the nextroller 24, upward and over the next roller 31, and so on until all ofthe rollers in the first compartment have been traversed. The apronsthen pass upward above the level of the tray 16 and over the roller29,which is ournaled, as aforesaid, over the first compartmentpartition16?, and then traverse the rollers 24 and 3l of the second compartmentin the same manner as those of the first. After traversing the rollersof the second compartment the aprons pass again above the level of thetop At one end of the framework 22- of the tray and over the roller 30,journaled over the second compartment-partition 16C.

After next traversing the rollers 24 and 31 of7 the roller 26, over theroller 25 o the diaphra m 22d, and back to the roller 23, from whic itstarted.

The aprons 34 and 35 are driven in all ofv their movements by therollers 26 and 36, said rollers being ofthe same diameter and revolvingat the same speed and being operatively connected together by toothedgear-wheelsl 37 and 38, mounted securely upon their ends, so that theupper one, 26, is positively driven by the lower. During all movementsof the rollers 26 and 36 they revolve in the direction indicated'bythearrows 39, and a detent 40 is mounted pivotally upon the lug 16e toen gage the teeth of the wheel 38 and prevent said rollers from beingaccidentally turned backward.

In order to kee the aprons 34 and 35 stretched taut at al times, thelower one, 35, is provided with an idle roller 41, which is mountedbelow the large roller 36, said roller 41 being supported and forcedyieldingly against said apron b3 two spring-arms 42, engaging thepintles of said roller and riveted to the end wall 16d, while the otherapron 34 is provided with a like roller 43, crowded yieldingly to it bytwo spring-'arms 44, engaging its pintles and riveted to the diaphragm22d.

The sides of the diaphragm 22d projectont over and clear of the sides ofthe tray 16 and have eyes 22i engaged by tension helical springs 45 and46, one, 45, of said springs having its lower end hooked around theprotuberance of the cock-opening 21b and the other, 46, having its lowerend hooked around .a stud 16i, projecting from the tray 16 for thispurpose. These springs act yielding] y to press the two rollers 26 and36 together to grip and drive the aprons 34 and 35 and also to press thetwo rollers 23 and 28 together, as aforesaid, and as the rollers 24 aremounted in the framework 22 and the rollers 31 in the tray the springsmust exert sufficient force to overpower the tension of the aprons 34and 35 and prevent them from lifting said framework 22 upward in thetray.

The shaft or pintle 36b of the lower aprondriving roller 36 extendsthrough the drawerfront 2 and is provided with a crank 47 for drivingsaid roller, said crank being provided with a stop-pin 48, insertedsecurely into the drawer-front for pur oses later described and beingmade of elastic sheet metal, so that it can be swung outward to passsaid pin.

z5. measurements of the rollers 49 an Mounted with their faces incontact with each other below the back wall 8 of the exposing-chamber 5are two rollers 49 and^50, whose oint of contact is in line with or 5slightly back of the front face of said wall. The mtles of these rollersare journaled in the u s 16g, projecting u ward from the tray, t epintles of the sma ler roller l50 engaging eyes 16k and those of thelarger roller ro 49 lyin in the end of the slots 16. These slots 16 areprovided with sliding blocks 51, which act against the pintles 49b toress the roller 49 into contact with the smal er roller 5'0, and saidblocks are backed up b screws 15 52'. It being necessary to remove t eroller 49 to allow the framework 22 to be taken out of the tray 16, theslots 1,6' are with outlet openings 16, throug 'which the pintles ofsaid roller may pass after unzo screwing the screws52. The rollers 49and 50 are jacketed with rubberor other suitable elastic material, sothat their gripping contact -is slightly yielding and more easilyadjusted by the screws 52. The eripheral 50 must be commensurate witheach other, so that a given point on the larger roller will always meett e same point on the smaller, this arrangement being required to allowthe use of a cutting or severing blade 53, which rojects from the faceof the roller 49 anrl passes the roller 5() by drop ing into thereceiving-groove 50b of said ro ler. This blade is shown separately inFig. 6 and fits tightly 3 5 into a lon itudinal undercut oove 49c in itsroller, an in order to certain y sever the film 15, that asses betweenthe rollers 49 and 50 as later escribed, the edge of the blade isserrated or toothed to have a puncturin effect on the film and render iteasily severe at the puncture-line.

The rollers 49 and 50 are operatively-connected with each other bytoothed wheels 54 and 55, whichA mesh with each other and are 45 securedpermanently to the ends of said rollers, .and the lar erroller 49 isoperatively connected with t e large apron-driving roller 26 at theopposite end of the structure by a link belt 56. This belt56 engagessprocket- 5o wheels 57 and 58, the wheel 58 bein mount-V int e 2Gb ofoosely upon ed securely upon the rigid end the roller 26 and the wheel57 the intle 49b ofthe roller 49.

T e sprocket-wheel 57 has an integral hub 5 5 extension 57h, providedwith inclinedteeth 57 C, and said teeth are adapted to engage the hookedendl of a detent 59, which is'secured pivotally tothe end of the roller49 through the wheel 54. The detent 59 is held normally into engagementwith the teeth 57c by a small spring 6() and 1s provided with an arm59h, extending radially with the roller 49. At each revolution of. theroller 49 and just as the blade 53 has fully entered or isjus't with- 65 drawing from its groove 5() the arm 59b ofthe rovided whichdetent 59is caught by a hook 61b on the end of a lever 61, which disengages saiddetent from the inclined teeth 57 C, and thus discontinues the movementof said roller 49 until a eriod of action-of other parts of the machine7c 1s completed. The lever 61 is secured piv'- otally at its centralpoint to a lug 16m, projecting upward from the tray 16, and its endopposite the hook 61b lies in the path of aprojecting pin 26', carriedby the roller 26, so 75 that at each revolution o said roller 26 the pin26c trips said' lever and causes the hook 61h. to release the detent 59.

In using the machine the compartments of the tray 16 are filled with thenecessary de- 8o veloping, ixin and washing solutions, and a spool 13 offi In 15 is mounted in the filmchamber 9. The end of the film is broughtup over the roller 62 and passed down through the exposing-chamber 5,and said film is then 85 caught by the two rollers 49 and 50, whichstretch it tightly upon the face of the wall 8 in position for exposure.Positioned beneath the roller 50 and attached to an upper edge of thedrawer 2 is a guiding-apron a. This 9o apron depends on a curve andterminates at.

a point above the plane 0f the rollers 28 23 and is intended to insurethe positive delivery of the severed portions of the film between theaprons 34 35. made the crank 47 is turned to drive the iprrrts and therollers 49 and 50' draw the rn down and insert its end between theaprons 34 and 35 at the rollers 23 and 28, a continued turning of thecrank 47 bringing 10o the o eration to a point where the film is severedy the blade 53, as aforesaid. At this point, as before stated, the hook61b on the ever 61 disengages the roller 49 from its driving mechanism,and said roller and its coact- 1o 5 ing roller 50 keep the film 15stretched taut in theex osin -chamber 5l for another exposure, w ile t eportion of film below said rollers is severed from the remainin supplyof film at the puncture-line forme by the no blade 53 and is drawn ondown into the developing solution by the aprons 34 and 35. Forconvenience in setting the film 15 for each exposure and in order tohave the exposed portions of film follow each other into 1 15 andthrough the developing solutions in proper order the mechanism is sotimed that the crank 47 shall abut the stop-pin 48 just as the exposedand detached ortion of said film has been completely submerged in the12o developing solution. To accomplish this and in view of the /factthat all rollers in the' machine have the same peripheral s eed, theperi heral measurement ofthe ro ler 49 is ma e less than that of theroller 26, by which i z 5 said roller 49 is driven an amountapproximately equal to the distance the film 15 will travel in passinfrom the contactoint of the rollers 49 an 50 to the surface o thedeveloping fluid. The pin 26 of the roller 26 13o After the exposure 1S95 i comes in contact with the lever .6l approximately at the sameinstantthat the crank 47 abuts the stop-pin 48, so that as said crank isslipped past said pin said lever is tripped and the roller 49 be ins itsrevolution with said crank, said ro ler completing its revolution andbeing stopped by said lever in time to allow the severed portion of filmto be submerged in the developing fluid beforethe crank again abuts thestop-pin. The exposed portions of film pass between the aprons 34 and 35through all of the developing, fixing, and washing solutions in thedifferent compartments of the tray, the Derforations of said apronsallowing the Huid to flow freely about said film, and the film isfinally delivered from between the aprons in the form of separatefinished prints through the delivery-opening 63 in the end of the casncases Where it is desired to run a sin le portion of film through thedeveloping so? tions without following it by other portions in regularorder the eccentric stop 64, mounted u on the spindle 65, is turned downagainst the'ldver 61, so as to stop all further revolution of the roller49, and when the lever 6l is thus locked its elastic properties willallow the pin 26o of the roller 26 to p'ass'it. One end of the spindleis mounted in and extends through a bracket or arm 66, depending fromthe top of the casin ,while the opposite end ortion of the spin leextends throu h and beyond a side of the casing. A turnutton 67 issecured to the exterior portion of the spindle for rotating the same.The cam 64 is secured to the Afree portion of the spindle adjacent thearm 66.
